An event-related potential study of deception to self preferences.
The spatiotemporal analysis of brain activation during the execution of deceptive decision-making was performed in 14 normal young adult subjects by using high-density event-related brain potentials (ERPs) with a delayed-response paradigm (subjects were required to hide their true attitudes for a moment). Our results showed that between 400 and 700 ms after stimulus onset, Deceptive items elicited a more negative ERP deflection (N400-700) than Truthful items, and between 1000 and 2000 ms, Deceptive items elicited a more positive ERP deflection (P1000-2000) than Truthful items. Analyses using dipole locations indicated that: (1) the generators of N400-700 were localized in the medial frontal gyrus (GFM) and middle temporal gyrus (GTM), which might be involved in conflict detection and control during deceptive decision-making; and (2) the generators of P1000-2000 were localized near the cuneus (CU) and the cingulate gyrus, which might be involved in conflict coordination in working memory due to deception.
